My 4 GB ipod nano has a blank screen but still lights up, blank with NO logo and I can play songs there is just no way to see what you are doing. I unplugged the ipod and the screen has been lit and blank since. I;ve tried plugging it back into the computer and turning it off, but nothing is working. what do i do? Same problem here too, works but no menu on the screen. It stopped during my running workout. I sent the unit to Apple who claims that it has internal damage related to a liquid. Poor service, what a crappy design for the money, I didn't expect a throwaway for what was spent.
